The question gives us the velocity of the wave and its frequency. Using these values, we can solve for the wavelength.
Example Question #1 : Velocity, Frequency, And Wavelength
What best describes how a wave is affected when it travels from one medium to another medium?
Possible Answers:
Neither speed not frequency change
The frequency changes, but the speed remains the same
The wave speed changed, but the frequency remains the same
The wavelength does not change
Both speed and frequency change
Correct answer:
The wave speed changed, but the frequency remains the same
Explanation:
It is a property of waves that the frequency remains constant and speed changes as it passes from one medium to another.
